Recombinant proteins were affinity purified and screened in ELISA with equine sera to identify immunoreactive polypeptides. The large envelope glycoprotein (GL) was identified as the most reactive to EAV-positive equine sera and an immuno-dominant epitope was mapped between amino acids 55 and 98 by subcloning and expression. A fusion protein covering this region and a GL-specific synthetic peptide (residues 75 through 97) induced EAV-neutralizing antibody in vaccinated horses. The defined antigenic region of GL is likely to be exposed on the surface of the native EAV virion and consequently may be useful in the development of diagnostic tests and vaccines.", }
